Answer:
The maximum current, in amperes, that a conductor can carry continuously under the conditions of abuse without exceeding its temperature rating.
Answer:
The answer is 4N or B
Explanation:
Just the equation W = F x D.
We have W = 8 J and D = 2 m using algebra ....
8J/2m = F ... F = 4.
Explanation:
Formula for maximum efficiency of a Carnot refrigerator is as follows.
..... (1)
And, formula for maximum efficiency of Carnot refrigerator is as follows.
...... (2)
Now, equating both equations (1) and (2) as follows.
=

= 
= 
= 2.5
Thus, we can conclude that the ratio of heat extracted by the refrigerator ("cooling load") to the heat delivered to the engine ("heating load") is 2.5.
The correct answer to this question is C - Gravity is a force. Gravity
is also an example of a universal law. Well, according to Isaac Newton,
anyway. According to Newton's Law of Universal Gravitation, 'every point
mass attracts every single point mass by a force pointing along the
line intersecting both paths.'

To develop this problem we will apply the concepts related to the Electromagnetic Force. The magnetic force can be defined as the product between the free space constant, the current (of each cable) and the length of these, on the perimeter of the cross section, in this case circular. Mathematically it can be expressed as,

Here,
= Permeability free space
I = Current
L = Length
d= Distance between them
Our values are,




Rearranging the previous equation to find the current,





Therefore the current in the rods is 210.6A
